“…There is a body of related work on guiding the choice of continuous parameters given the abstract action sequences (Chitnis et al, 2019;Kim et al, 2018Kim et al, , 2019a. In particular, we directly build on our previous work on using GANs for learning a sampler (Kim et al, 2018(Kim et al, , 2019a, but in this work we use advanced GAN training technique that offers much more stable training (Gulrajani et al, 2017).…”
